Where is the data for the examples in the tutorials directory?

In every example says 'PATH/TO/DATAFILE' but the only data i see in the data folder (in the same directory is for the titanic. on the following page it looks like where you would find data but the iris data doesn't work with the existing code and the mnist data wants you to put in a user name and password for someone's server which is clearly wrong.

The link to where I would think to download the data

Thanks!
